Fixes build with --disable-muxers --disable-network.

Thanks to Hendrik Leppkes for noticing.

Only fixes MPEG-1/MPEG-2 as a first step.

CONFIG_VDPAU is the condition on which ff_vdpau_mpeg_picture_complete
is compiled in, so it is more appropriate, particularly since the
separate VDPAU decoder should be removed in the longer term.

Since we now always allocate it, it can simply be made part of the context
instead.

thread_count passed to ff_thread_init() is only used to set AVCodecContext.
thread_count, and can be removed. Instead move it to the legacy implementation
of avcodec_thread_init().

This also fixes the problem that calling avcodec_thread_init() with pthreads
enabled did not set it since ff1efc524c.

This is done by adding a setsar filter at the beginning of the
configured filterchain.

This implementation is more robust, since does not modify the
filterchain description (which was creating potential syntax errors),
but directly modifies the filterchain structure.

This also changes the ffmpeg -aspect behavior, as following filters in
the filterchain can change the DAR/SAR set by the inserted setsar
filter.

Currently, the parser is buggy and only processes the stream extradata
when the flag is set. This fixes it to actually inspect the frames.

Whitespce will be fixed in a separate change.

I think the documentation of sameq is causing confusion and misuse of
this option.

swscale doesnt ever actually do any runtime detection at all when
runtime cpu detection is enabled, it simply passes whatever is passed
to -sws_flags, which could be nothing at all making swscale default to
the C implementation.
